    UFH pump not turning on

    Hi all, I've noticed that my UFH pump is not always turning on as soon as the stat & valve calls for heat. This results in hot water passing through the underfloor pipes but without being pumped, which means it takes forever for the room to heat. From testing with a multimeter I see that it's...

    UFH actuator fault. Causes?

    What can do this to an actuator? Overvoltage? Wear and tear? Stuck pin on the valve? This is in the German built kit house I’ve done work in before. The actuator controller is powered separately to the central heating boiler.. each room has a stat, which then opens one or more actuators for...
